Use properties of Fourier Transform to solve the question. The question is in the imgur link below.

I got $f_t$ of $\frac {sin(pi \cdot t)} {pi \cdot t}$ as rectangular pulse with value $1$ from -pi to pi second ft is $e^{-jw}$ from $-2 \pi$ to $2 \pi$. I'm unable to get the resultant of two of them

    $\begingroup$ We don't solve other people's homework when they don't even show any own attempt and explain exactly what they personally need help with. In fact, we have a question close reason for exactly that. $\endgroup$ – Marcus Müller Oct 7 '20 at 12:19
  • $\begingroup$ Also use some Latex to clarify that equation. Are all those " * " s stand for "multiplication" ? Or is one of them a convolution ? $\endgroup$ – Fat32 Oct 7 '20 at 12:21
